In my past experience, hot chips are usually in backwards. Also look
for any bent pins or shorts.

Greetings folks,
Just got myself a K2 (yay!) as it sure makes for a very nice rig and
kit to build.
I've just completed the control board, front panel and the minor
assembly on the RF board. Upon power-up, there's NO smoke (yeah!) but...
I did notice that the area of the control board where U3 is located
seemed hot. At first I thought this was attributed to the regulators
directly below it. Instead, I'm now feeling (and I mean feeling!) that
U3 is pretty hot. I managed to just run the DISPLAY test to fetch the
voltage and saw it show "E 17.8 i .68"
Now, I did test the power supply, and it's happily putting out 13.8V all
the way through the RF board. But it looks like a simmering U3 and the
display are pointing to something wrong with the voltage and current
sensing circuitry. Am I on the right track?
Thanks
